Software Walkthrough

| 00:01 | In this worked example, we're going to be looking at the launch control setup in a Link G4 Plus or ViPEC Platform. |
| 00:08 | And for our worked example, we're going to be using, on this end, 350Z with a plug and play ECU. |
| 00:14 | However, the settings and the configuration we're going to look at, are applicable across the range of the Link G4 Plus and ViPEC I-series products. |
| 00:25 | So, we're gonna start with a very brief overview of where the particular settings are in the software, that you're going to need to look at. |
| 00:33 | And we can look at that now, if we look at the ECU settings. |
| 00:39 | And there's a couple of different areas we're going to need to look at. |
| 00:43 | The actual launch control setup is found under the "Motor Sport" tab, here, under "Launch Control" And we can expand that out to see our control functionality. |
| 00:55 | However, before we even start looking at launch control we're also going to need to setup some wheel speed sensors. |
| 01:02 | And on this particular car, we're getting all of that data in via can. |
| 01:06 | So, it makes our job a little bit easier. |
| 01:09 | All of the wheel speed data is coming via the ABS computer. |
| 01:13 | And in a conventional sense though, we would need to setup wheel speed sensors. |
| 01:17 | And these would be done through a digital input. |
| 01:21 | And we can choose the function from the drop down menu, and then decide on which particular input we want to see wheel speed from. |
| 01:33 | And we can choose that, and then setup the sensor. |
| 01:36 | We can also calibrate it to suit the diameter, and the number-- The diameter of the wheel and also the number of pickups per revolution that the sensor is seeing. |
| 01:48 | So, we need to do that first. |
| 01:49 | As I say, our data is coming via can. |
| 01:52 | Another area we do need to look at though, is the allocation of those wheel speed sensors and how that's going to be used by the software. |
| 02:02 | And that can be done down in the Chassis and Body menu. |
| 02:06 | And you can see we have the option here that's called "Speed Sources". |
| 02:10 | Now if we click on that, we can choose our--, what speed source will be used as our driven wheel speed and our non-driven wheel speed. |
| 02:18 | And normally, if we've got sensors fitted to all four wheels, which we do here, we will be wanting to use the average of both the front and rear. |
| 02:26 | Particularly, with a two-wheel drive car like this, you wanna use the average, which will take into account if you've got a loose differential, which allows some inside wheel spin. |
| 02:39 | So, that's where we want to do our input configuration. |
| 02:43 | Then we can have a look now at our actual launch control menu. |
| 02:48 | And we've got our options as to how we want to configure the launch control. |
| 02:55 | And all of the actual setup and tuning of the launch control system is going to be done inside this menu structure here. |
| 03:02 | So, in the next section we will look at the actual configuration of the launch control system. |
